I just received a press release from InsiderAdvantage detailing the results of a poll which finds Mitt Romney and Newt Gingrich in a dead heat among Republican presidential candidates, with Rick Santorum and Ron Paul tied for second. The poll of registered voters was conducted in South Carolina Wednesday night.

Here is the breakdown:

Mitt Romney: 23 percent

Newt Gingrich: 21 percent

Rick Santorum: 14 percent

Ron Paul: 13 percent

Jon Huntsman: 7 percent

Rick Perry: 5 percent

Other: 2 percent

Undecided/No opinion: 15 percent

Conducted January 11 among 726 likely voters, for a margin of error of plus or minus 4 percent.

“Romney and Gingrich are even among those who identify themselves as ‘Republicans’ in South Carolina. Among those who call themselves ‘Independent’, Paul leads at 29 percent, but Gingrich and Romney are not far behind, said, Matt Towery, CEO InsiderAdvantage. “Men favor Gingrich, while women favor Romney. Most of interest, Santorum preforms well among voters age 30-44, hold his own among women, but does poorly with male voters.”

Well, the undecideds are a big chunk and this race is anybody’s to win, in terms of the frontrunners, if they can win over these undecideds. It should also be noted that another poll finds Mitt Romney slipping in South Carolina and now leads Newt Gingrich by two points.
